Performance :: CPU Throttle Even On High Performance Power Plan
Nov 16, 2015
I have been having some really annoying performance problems after upgrading my laptop from win8 to win 10.
My laptop is a asus ux32vd, with an Intel i7-3517U cpu.(normal core speed: 1.7ghz, turbo: 2.4ghz)
CPU-Z is showing ~990mhz constantly, no matter how high load there is on the cpu, and what temperature it is(usually around 50-60C).
I just cant figure out what is going on, and why it keeps throttling. Everything is running really slow, chrome is slow, facebook is tough to scroll through. Tried resetting the power plans to default, that didnt work. sometimes it works for changing power plan, and the restarting, but its not consistent at all. What it could be?

I've notice that on windows 10 and 8.1, task manager would show the my max cpu core speed is 2.3-2.4 ghz. However, my Core 2 Quad q8400 is rated at 2.66 ghz. I tried changing the power settings in windows and try lowering my cpu temperature, but my speed would never reach 2.66 ghz.

In W10 when I leave my laptop in sleep mode overnight, it uses about 10% of battery life. In windows 7 it was way less, to the point that it wasn't even noticeable.
where I should start looking?
I have a Thinkpad X220T

I recently upgraded Windows 7 to Windows 10. When I power down the system from the menu, my computer does not completely turn off. The procedure I use is described below:
Click Windows_Start_button > Power > Shutdown
The system closes applications and appears to initiate a shutdown procedure. Everything appears to be shut off, but my mouse is still lit up. I do notice that the fan stops and everything else appears to be completely shut down. When I was running Windows 7 before my upgrade, my system completely powered down.
I have a dual boot system with Linux, and when I power down from Linux, the shutdown is complete, so I don't think I accidentally did anything to the hardware or BIOS.

My brother favors to choose Shut down when I close the Lid, whereas I prefer Sleep mode.If I change, it changes for my brother's account also.I do not want this.I suspect there might be something useful in Group policy>user configuration but I am not sure.

I just recently installed Windows 10 on my Dell Inspiron Laptop and so far I am not impressed at all - in fact, I am very seriously debating one of two actions - re-install Windows 7 or switching to an entirely different OS.
The reason for reverting to Windows 7/switching OS are as follows:
1) Currently with an idle system (i.e. no applications running at all), an svchost process is using anywhere from 40 to 60% of my cpu. When I did a tasklist on this process the following processes are attached to this one pid: Appinfo, BITS, Browser, DsmSVC, IKEEXT, iphlpsvc, LanmanServer, lfsvc, ProfSvc, Schedule, SENS, ShellHWDetction, Themes, UserMananger, Winmgmt, wuauserv. My question is this - is it necessary for these processes to be run. If they are, then am I looking at only being able to use 50% of my processor (since this one pid is using the rest of it)?
2) For a virus scanner - I am using McAffee and under Windows 7, it took my laptop 24 hours to scan 231 GB of data. Since I switched to Windows 10 (Same hardware, same memory, etc) it now takes my virus scanner over 48 hours to scan 231 GB of data.
3) If I had not been poking around and trying to change my update settings, I would never have found out that Microsoft expects their users to update the windows of the other users (Microsoft calls it Dynamic Updates). Now this is all well and good if some one had said something since I would have loved to know about it sooner since I am on a metered service.
4) Some of the programs that comes with Windows 10, I have no use for but yet I can not un-install them (Cortana come to mind).
5) It appears that even though I have turned off "Live tiles" the tile continue to update from the net (again - it would have been nice to know since I am on a metered service).
The only option that I know of is to revert back to Windows 7 or switch to a new OS.

I'm getting a constant high disk usage without even having anything running. Here's a screenshot of my problem
And well, so far I've tried the ''deactivate 'windows search' and 'superfetch''' and it hasn't really done the trick.
Also I resetted my pc yesterday, as of now I'm running a clean install of Windows 10.
Did the ''turn off notifications from Windows'' and really nothing, I've also defrag quite some times with Defraggler and DiskDefrag and nothing.

Basically I noticed that my PC has a lot of RAM used but no program is using the RAM - see attached screenshots. Obviously it doesnt really affect me until I launch a game: eg GTA 5 which before ran happily at 60 and is now stuck on less than 1 FPS when I get into the game (even after spending like 20 minutes in lag hell to try to reduce all the settings to the lowest).
However Rainbow Six Siege runs at 120 FPS with no issues, so GTA may be an isolated incident.
(Also important to note I only have 8Gb of RAM, even though it says */16.0GB for the committed memory)

I have recently noticed a bit of a performance issue on my HP laptop running Windows 10 Home.
What happens is, if I am not doing anything on the laptop, but am not putting it to sleep (i.e. idling), it stays at a low CPU usage. However, after a while (usually about a minute?), the CPU usage rockets up, and also affects my CPU temperatures (goes up from ~35'C to ~50'C).
The processes that are the culprit, as defined by the detailed tab of Task manager, are either "svchost.exe" or "System" - the latter is described as "NT Kernel and System" and is linked to ntoskrnl.exe.
The laptop came preinstalled with Windows 10 and doesn't have many programs installed.

Is there some way to create a power plan toggle similar to the brightness toggle when clicking on the battery in the notification area? My googling doesn't seem to come up with anything.

so i migrated from windows 7 to windows 10.im running windows 10 pro,64 bit,4gb ram on intel i3 processor.in windows 7 when i click on the battery icon i can choose the power plan setting immediately. but in windows 10,when i click the battery icon the power plan option is no longer there.i had to go through advanced power setting to get to the power plan settings.so i wonder is there any way to get the power plan setting to show directly when i click the battery icon?i knew there was a workaround by editing registry and showing it by right clicking on desktop instead but i prefer the old way.

So up until this morning my Windows 10 desktop has been performing really well. When the machine is idle the CPU use is only in the 1-3% range.
For some reason my idle CPU use is now CONSTANTLY 30-40% (even after a reboot)! Task manager says its "Service Host: Local System (15)". If I expand this process in task manager it lists:
Why is this happening all of a sudden? I have all Windows Updates installed and I run an i7-3770 CPU.
My machine is now slow/sluggish with 30-40% being hogged by these services!
I don't have any Malware installed as I run Malwarebytes Premium and the scan comes back clean. Some goes for a full anti virus scan.

After installing Windows 10, I have consistently been getting high memory and cpu usage by both the System and Service Host: Local System processes. Usually the usage keeps rising from 1GB to sometimes 8GB. I left my comp on while I was at the gym today and came home to it prompting me with a low memory available message. This must have shut down some processes because now my pc is running at 13% memory and 2% cpu. I have searched for this issue and found similar threads, but none of the solution work for me.

Here is my laptop specification:
- HP Pavilion g4
- Intel Core i3 2.2 GHz
- Radeon 6470m (but somehow got 7400 driver and worked) plus Intel HD 3000
- Windows 10 of course
- 2 gigs ram
- And latest drivers, checked with Uniblue's driverscanner and link on other subforum stickies.
It's high memory usage of this process, it starts with ~7mb then grows up to ~200mb on heavy use. This happen with recently windows 10 update.
What I have done is, I do a restart every time I made these changes:
- SFC /scannow
- Update driver (again)
- Turn windows 10 tips off
- Try disable Superfetch
- Malwarebytes scan
- Disabling High Definition Audio driver drops the process usage to normal 28kb, but this somehow rise again to ~100mb.

I just upgraded to TH2 from Win 10 Pro. I noticed that my disk usage is near 99% for the past 20 mins. It keeps fluctuatiing between 10 to 99. Normally my disk usage stays at 0. May be this might be Windows settling in after the upgrade? There was high disk usage the first time around when i upgraded from Win7.

I just installed win 10 last day, and it was going fine, no conflicts on the drivers whatsoever. But after a day, when I booted up, it seems to have slowed down to a point that everything does not respond to my inputs, though it does after a couple of minutes, i check the task manager and it shows that the disk usage is high, the r/w speed show high utilization about 10-40mbps and the active time is 100%? I have read some thread and suggested to turn off superfetch and prefetch but that didn't do a thing to me. Btw, I installed it over win 8.1 using a bootable usb.

I never had it before and started to happen with these recent updates.

From sometime in October, after an update, there have been periods, sometimes intermittent, sometime persisting for a long time, when Disk usage spikes up to 100%, and makes a lot of things unusable.
I did some researching, and disabled a bunch of stuff, like Windows notifications, Windows search, background intelligent transfer and superfetch, even OneDrive, but even on Windows 10 version 1511, Disk usage spikes to 100%, the offending application / service being anything from System to memory compression to 3rd party applications...
This is becoming extremely irritating, and my video playback or something else stutters a lot when disk usage jumps up, often at chronic levels, then backs down, or stays at that usage for some time.

I opened my computer after having it been asleep all night; everything was working fine until I realized that my sound volume was stuck at a high level and no matter what I changed the volume to, it would not go down. Having had issues with my sound drivers before, I solved this by reinstalling the sound driver. I figured this would be the end of my issues for the day and restarted the computer to finalize the installation. Then windows installed updates, and when I got back into the system, I realized something was wrong. I have Advanced System Care 9, which comes with a real-time monitor of system usage (RAM and CPU), and I noticed that the CPU usage was much higher than it should be--usually it will be around 1-5% when I am not running anything (or just a few programs), but instead it was using 20-90% CPU, and the RAM would not go any lower than 24%.
However, I had had this issue before; Bitdefender Antivirus had started acting up a few days ago using up 90-100% CPU, and I had caught it using Microsoft Process Explorer. Removing Bitdefender solved the problem. So, naturally, I went to the process explorer to check what was using so much CPU again. But this time--nothing. The windows process explorer showed nothing using that much CPU. From there, I began to notice the rest of the problems: many functions of the task bar would not work, such as any of the toolbar icons, or the windows icon, or Cortana. Firefox would not open, either, and I could not get Steam to connect.
Also Ctrl+alt+delete did nothing but bring up an endless black screen, as did restarting. The only way to reboot is to force it by pressing the power button. Therefore I could not reach safe mode. From there I ran a myriad of virus/malware/adware scanners/cleaners/optimizers, none of which found or did anything to fix the problems, though my computer is now squeaky clean otherwise! Eventually I managed to get into safe mode by a very finicky method, which was by turning the computer off during startup which made it do a startup repair next time it turned on, from which I was able to enter safe mode.
And in safe mode--everything works. None of the described issues happen there. I am able to use all the windows features (aside from those blocked in safe mode), ctrl+alt+delete and restarting function properly, and I am able to connect to the internet and use firefox, everything works. So this means that there is something there causing the problems, and it is being blocked by safe mode, but I cannot find it! After running several more scanners, all of which found either nothing, or only small innocuous things, I ran Microsoft Safety Scanner, which found a "severe" trojan which was (I believe) called Dynammer!ac, and I figured this must have been the culprit--but no. Restarting and returning to normal mode resulted in the same problems occurring. Since then I have uninstalled/reinstalled a few drivers that were suggested to me to try, such as sound (the one that I had to replace before the problems started), and the display drivers, none of which fixed anything, either.

When I am downloading something with utorrent the memory usage in task manager slowly creeps to 100% and makes my computer unusable and even if I shut down utorrent the memory usage does not change and I have to restart my PC. Same goes for browsing facebook or any other sites. Is there a solution to this? I really don't want to reinstall my system.

I installed Windows 10 (10130 build) and I love it. The only problem that I'm having with it is this Photo Background app that eats my cpu(30-40%)! When I start up windows I need to kill it in task manager everytime. But even after I kill it if I leave my laptop in idle it still comes back. I want to understand what this Photos Background Task Host is doing, his functionality...

from some reason, a process called "Windows Image Acquisition (WIA), which I've never seen before is running and using about 30% CPU. I read in MSDN that "Windows Image Acquisition (WIA) is the still image acquisition platform in the Windows family of operating systems starting with Windows Millennium Edition (Windows Me) and Windows XP."
Does that mean that from some reason my laptop's camera is running now? Maybe my laptop was hacked?

Since upgrading from windows 7 to 10 my pc has been slowed down to a crawl by periods of very high cpu usage. A major culprit, but not the only one, is local security authority process.
This makes the laptop overheat , reduces battery life and slows work to a crawl. I have run sfcscannow and dism as administrator and no fault has been found..

From the moment I switch ON my desktop until switching OFF (working for 12 hours) the local system service host is always between 30% to 40% regarding CPU usage.Why? How to stop it?
This does not happen in my Microsoft Surface Pro machine. Both machines, desktop and Surface have the same software installed so it's hard to believe this CPU usage is software based.

So i just upgraded from Windows 7 to Win10 a week ago and everything went smooth as silk. I will said this is the first time i can remember doing an in place upgrade, I always format and do a clean install about once a year but ive been busy so i took the lazy route.
Issue is i have my power settings set to None and my power options set to turn the monitors off after 10 minutes. I have it set to Never sleep. After the 10 minutes passes the monitors power off as expected but when i move the mouse or hit keys on my keyboard it takes at least 10-15 seconds to initiate the monitor power on. This was 1-2 seconds in Windows 7. Its pretty minor but its irritating as hell.
